Range is the difference between the greatest and the lowest value in the given set of data. Finding range for a given

datainvolves three steps.

Step 1: Arranging the given data in ascending or descending order

Step 2: Find the largest number and smallest number in the data

Step 3: Finding the difference between them.

Example 1: Edward wrote 7 exams in Mathematics and secured 78, 91, 48, 68, 94, 66, 79 in his tests. Find the range of his

test scores.

Step 1: Arranging the data in ascending order

48, 66, 68, 78, 79, 91, 94

Step 2: Finding the largest and smallest number

Largest number = 94

Smallest number = 48

Step 3: Finding the difference between the largest and smallest numbers.

Range = 94 – 48 = 46

Hence the range of his test score is 46.

Example 2: Hourly wages of the employee are \$5.50, \$7.80, \$18.20, \$8.60, \$12.40, \$6.00, \$9.30. Find the range of the above

data.

Step 1: Arranging the data in ascending order

\$5.50, \$6.00, \$7.80, \$8.60, \$9.30, \$12.40, \$18.20

Step 2: Finding the largest and smallest number

Largest number = \$18.20

Smallest number = \$5.50

Step 3: Finding the difference between largest and smallest number.

Range = \$18.20 - \$5.50

= \$12.70

Hence the range of the wages of employee is \$12.70.
